It's very niche because the colour is limited and it needs sunlight or frontlight. Filters on top on mono eink which has only black, white and 14 grey levels. That's Triton or Kaleido. Forget Gallery unless there is a tech breakthrough as it's a 1.5 second page refresh even though it's a real coloured panel, not mono eink with a filter.

Samsung and LG have 4K HDR screens (28″ and 23″) that are like paper to use and a fraction of the price of the Dasung 25" which is no use for anything other than text or comics.

Even the mono 13″ plus eink are mostly lower resolution than 300 dpi. Most used to be about 200 dpi and aimed at the Digital Paper Tablet niche market and can be very expensive.

We'll see more 300 dpi 10.3″ mono models.

Certainly a 13″ colour eink would be nice for comics. But above 11″ the front light is tricky and uneven. Also at best the colour resolution is half the native panel, so a 13″ panel about 230 dpi is only 115 dpi as a colour display. There is one 10.3″ colour eink using the 300 dpi panel similar to a Kindle Scribe, so it gives 150 dpi.

I'd consider a 12″ to 14″ colour eink if it had a decent even front light (which needs 5 to 10 times the power of a 7″ mono ereader for same brightness) and had 200 dpi or more colour resolution. But it's a niche in a niche.
